LOOM.

Specification of Letterslatent.

Patented Feb. 25', 1919.

Application filed September 17, 1917. Serial No. 191,672.

To all whom it may concern Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, residin at Hopedale, county of WVorcester, and tate of Massachusetts, have invented an Improvement in Looms, of which the follow-- ing description, in connection with the accompanying drawing, is a specificatlon, like characters on the drawing representing like parts.

This invention has for its object the provision of means-to prevent the filling in the shuttle from being thrown by momentum out of the shuttle recess at the time the shuttle is boxed.

In the case particularly of heavy grades of filling such as employed in weaving duck or other heavy materials, the sudden stoppage of the shuttle when boxed at the end of the pick causes the filling to be thrown off the end of the filling carrier by momentum and thrown up more or less out of the shuttle recess. In the case of automatic weft replenishing looms and other looms employing a self-threading shuttle, the result is not infrequently to cause the shuttle to unthread by the fillil being thrown out through the threading s 0t and in the case of these and other types of looms, the result not infrequently is for the filling to be caught between the shuttle and the blnder and other parts of the loom and be pinched or broken or entangled.

This invention provides means, such for example as a pad of bristles which extends over and covers the filling on the filling carrier in the shuttle recess at the time the shuttle is boxed and thus prevents the filling from being thrown by momentum out of the shuttle recess upon the sudden stoppage of V the shuttle. These means are preferably supported from the frame of the loom so as to be out of the way of the mechanism for efiecting transfer if the loom be of the replenishing type.

These and other objects of the invention will appear more fully from the accompanying description and drawlng and W111 be particularly pointed out in the appended claims.

The drawings represent so much of a loom of the automatic weft replenishing type known as the Northrop loom as is necessary to disclose the invention together with a preferred form of the invention embodied therein.

In the drawings,

Figure 1 is an elevation partially in vertical cross-section of a portion of the loom looking toward the transfer end;

Fig. 2 is a top plan view of a portion of the 100m shown in Fig. 1. r

The present invention is not concerned with the particular type or construction of loom and that type of loom illustrated is presented simply to efiect the disclosure of the invention.

The loom shown is of the well-known fNorthrop type. The loom side 1 constitutlng a portion of the loom frame carries the hopper 2 containing the supply of fresh filling carriers 8. When replenishment takes place, the usual transferrer 4 is operative to force a filling carrier out of the hopper into the shuttle then on the lay therebeneath and thereby to force out from the shuttle the exhausted filling carrier.

The lay 5 carried by the lay swords, one of which 6 is illustrated, carries on each end the usual shuttle box 7 the one at the transfer end of the lay being herein illustrated.

The shuttle 8 is recessed at 9 from topto bottom in the usual manner to receive .the filling carrier herein shown as a bobbin 10. When the shuttle is of the selfthreading type such as is used in the automatic weft replenishing loom, it is provided with some form of slot extending from the recess 9 into the eye from which the filling extends and in threading the shuttle the filling is simply drawn off from the filling carrier and passed down through these slots until it enters and reeves out through the eye. In the case of the automatic loom, this threading of the shuttle is performed automatically.

In the course of the operation of weaving, at the end of each pick, the shuttle is suddenly stopped by contact with the picker 12 and suitable mechanism such as a binder or loom check. When the filling is of a heavy weight, such as employed for example in the weaving of duck and other coarse materials, the weight of the filling is such as to give it considerable momentum. Consequently upon the sudden stoppage of the shuttle, at the time it is boxed at the end of the pick, the filling, especially that porthe stoppage of the shuttle.

tion next to be drawn off from the filling carrier, and that portion extending from the filling carrier to the shuttle eye, is lifted or thrown by its momentum and not infrequently is thrown up out of the shuttle recess. This results, in the case of the selfthreading shuttle, in the filling being thrown out of the threading slot thus unthrea'ding the shuttle or it results in the filling being caught between the shuttle and the walls of the shuttle box or the binder or other, parts of .the loom and becoming pinched, caught or broken.

This invention provides means for preventing the filling from thus being thrown by momentum out of the shuttle recess upon Such means may/be provided at both sides of the loom if found desirable but are particularly of use at the transfer end of the loom herein illustrated, Where the tendency is to throw the fillingv off the end of the filling carrier.

Preferably, this means is carried by, or supported from, the loom frame so that it does not move with the lay and consequently does not interfere with the operation of the transfer or replenishing mechanism. But

' cured thereto, as by the screws 15, a plate 16 which in the form illustrated is provided on its lower face with a pad of bristles 17. This plate is of sufficient area to cover the filling in the shuttle recess which is likely to be loosed and thrown out of the shuttle recess by momentum upon the stoppage of the shuttle and is herein shown as covering all the filling on the filling carrier in the.

shuttle.

The provision of a pad of bristles has been found an effective expedient for holding the filling in place and enabling the device to be Copies of thispatent may be obtained for vice from the loom frame, it is held in.

position out of the field of action of the transferrer but in a position where it secures the desired result.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A loom comprising a lay, a shuttle box on the lay, and means extending over and substantially covering the body of filling on the filling carrier in the shuttle at the time the shuttle is boxed whereby the filling is prevented thereby upon the stoppage of the shuttle from being thrown by momentum out of the shuttle recess.

2. A weft replenishing loom comprising a lay, a shuttle box on the lay, and means carried by the loom frame and extending over and substantially covering the body of filling on the filling carrier in the shuttle at the time the shuttle is boxed whereby the filling is prevented thereby upon the stop:

page of the shuttle from being thrown by momentum out of the shuttle recess but without interfering with the action of weft replenishment.

3. A loom comprising a lay, a shuttle box on the lay, a self-threading shuttle, means carried by the frame and extending over and substantially covering the body of filling on the filling carrier in the shuttle at the time the shuttle is boxed whereby the filling is prevented thereby upon the stoppage of the shuttle from being unthreaded from the shuttle by momentum.

A loom comprising a lay, a on the lay, a pad of bristles supported from the frame, and extending over and covering the filling on the filling carrier in the shuttle at the time the shuttle is boxed whereby the filling is prevented thereby upon the stoppage of the shuttle from being thrown by momentum out of the shuttle recess.

In testimony whereof, I have signed my name to this specification. I
